DOOR-CHECK.

Specification of Letters Patent.

Patented J1 uly 10, 1917..

Application filed May 2, 1917. Serial No. 165,873.

To all whom it may concern.-

Be it known that I, JULIUs A. LEVY, a citizen of the United States, residing at Walla Walla, in the county of Walla Walla and State of Washington, have invented certain new and useful Improvements in Door- Checks, of which the following is a specification.

This invention relates to devices applicable to. doors for preventing the same from slamming, the device being in the nature of a buffer which is struck by the doorwhen it closes, and which checks and cushions the movement of the door.

It is the object of the present invention to provide a novel and improved device of the kind stated, and also one which is simple in construction and highly efficient in operation, and which can be easily applied.

The object hereinbefore stated is attained by means of a combination and arrangement of parts to be hereinafter described and claimed, and in order that the same may be better understood, reference is had to the accompanying drawing forming a part of this specification.

In the drawing- Figure 1 is a perspective view of the device, and Fig. 2 is a horizontal section thereof in place.

Referring specifically to the drawing, 5 denotes a swinging door which closes against a stop 6 on the jamb 7 of the door frame. The check or bufi'er is mounted on the jamb, it being so positioned that it intercepts the door when the latter is swung to close, and said device comprises the following parts:

A base plate 8 is set into the face of the jamb 7 on one side of the stop 6, this plate being secured to the jamb by screws or other suitable fasteners 9, and having at one end a lateral flange 10 which seats over the edge of the jamb. On the rear face of the plate 8 is a cylindrical tube or barrel 11 which is fixed to the plate in any suitable manner, or which may be formed integral therewith. In the plate 8 is a longitudinal slot 12 extending horizontally and registering with a slot 13 in the tube 11. In the tube 11 is slidably mounted a plunger or stem 1d having at one end a laterally extending head 15 which is elongated vertically and joined to the stem by a neck 16 passing through the slots 12 and 13. The head is located on the outside of the plate 8 and it is slidable horizontally along the outer face thereof.

The tube 11 houses a spring 17 which bears on the neck 16 and urges the stem 14: in a direction outward of the edge of the stop 6 against which the door 5 closes. The head 15 extends into the path of the door, and hence when the latter closes it strikes the head and forces it toward the stop, this movement of the head being opposed by the spring 17. It will therefore be seen that the head acts as a spring bufier to check the movement of the door, and the latter closes against the stop 6 without slamming. The head is presented squarely to the door and may be covered with rubber or some other suitable cushioning material 18.

The jamb 7 and stop 6 will be recessed, as shown at 19, to accommodate the tube 11, the jamb recess being covered by the plate 8. The edge of the door stop 6 also has a recess 20 into which the buffer head 15 passes when the door is closed so that the latter may come squarely against the stop.

he device is simple in construction and it can therefore be cheaply manufactured and sold. The bufl'er head 15 extends transversely of the plate 8 on opposite sides of the slot 12, whereby it is guided and made to travel without the neck 16 binding in the slots 12 and 13. l/Vhen the device is used on double doors, it will be placed in the head or upper part of the casing.

I claim:

1. A door check comprising a base plate having a slot, a plunger stem located behind the base plate and having a laterally extending neck passing through the slot and provided on the outside of the base plate with a bufier head, a spring coiled around the stem and bearing against the neck there of, and a housing carried by the back of the plate and inclosing the spring.

2. A door check comprising a base plate having a slot, a plunger stem located beof, a spring coiled around the stem and hind the base plate and having a laterally bearing against the necki thereof, and a extending neck passing through the slot housing carried by'the back of the plate and 10 and provided on the outside of the base inclosing the spring.

' plate with a butler head extending trans- In testimony whereof]: afiix my signature. V

versely of the plate on opposite sides of the slot and slidable along the outer face there- JULIUS A. LEVY.
